Buffer overflow in Mozilla Maintenance Service and Mozilla Updater

Description

Security researcher Seb Patane reported stack buffer overflows in both the Maintenance Service and the Mozilla Updater when unexpectedly long paths were encountered. A local attacker could pass these as command-line arguments to the Maintenance Service to crash either program and potentially lead to arbitrary code being run with the Administrator privileges used by the Maintenance Service and inherited by the Updater.
